Helgi Rúnarsson successfully defended his PhD thesis "Kerr black holes with scalar and Proca hair". The exam took place at the University of Aveir, on October 9th 2017. The thesis was supervised by Gr@v members C. Herdeiro and E. Radu and former member J. C. Degollado, now at UNAM (Mexico). Congratulations Helgi!

Abstract: At the end of the 19th century the existence os a planet beyond Neptune was in debate. In 1930, Pluto was discovered, but too far from the prediction. In 1992 we found out that Pluto is actually a member of a huge belt of icy bodies orbiting beyond Neptune.
Abstract: Active galactic nuclei (AGNs) are extreme astrophysical environment that result in copious emission of X-rays. I describe how large archival datasets from X-ray telescopes can be used to search for new physics using the X-ray spectrum of AGNs.
For the second time C. Herdeiro was the guest interviewee of Porto Canal's "Mentes que Brilham". Watch and listen to the conversation (from minute 18 onwards) (Watch and listen to the first interview) with interviewer Cláudia Fonseca about black holes and some of the research work made at Gr@v in this area.
